Answer:
KM = 4
Step-by-step explanation:
The point of the segment addition postulate is that the combined length of segments laid end-to-end is the sum of their individual lengths.*
KL +LM = KM
(5x +1) +(3x +3) = 5x +4
8x +4 = 5x +4 . . . .simplify
3x = 0 . . . . . . . . . . subtract 5x+4
x = 0 . . . . . . . . . . . divide by 3
Then the length of KM is ...
KM = 5x +4 = 5·0 +4 = 0 +4
KM = 4

* Sometimes it seems that geometrical theorems simply state the obvious. Some interesting math arises from systems of geometry in which this is not true. We usually don't study those in high school.
Pick out the like terms. 6x^2 (which equals 36x), 11x, 2x^2 (which equals 4x), -17x.
36+11+4= 51, -17= 34x
-3+-4= -7
The simplified expression would be 34x+-7.
(This could be wrong though, I'm sorry if it is ^^)
The answer is: " 312.5 " .
_________________________________________________
<u>Note</u>: In the pattern given, each number is multipled by "5" to get to the number consecutive number.
__________________________________________________
The pattern given is:
__________________________________________________
" 0.5, 2.5, 12.5, 62.5, ____, ....." ;
Note: The first number in the pattern given is: "0.5" .
"0.5 * 5 = 2.5" ; and "2.5" is the second number in the pattern.
"2.5 * 5 = 12.5" ; and "12.5" is the third number in the pattern.
"12.5 * 5 = 62.5" ; and "62.5" is the fourth number (and final number SHOWN in the pattern).
To find the next number, we multiply "62.5" by "5" ; to get: "312.5" .

Answer: It would be 8+4z because you can't add a variable.
